World-renowned physicist and author Stephen Hawking presents a revolutionary look at the momentous discoveries that changed our perception of the world with this first-ever compilation of five classic works of physics and astronomy. His choice of landmark writings by some of the world's greatest thinkers traces the brilliant evolution of modern science and shows how each figure built upon the work of his predecessors. On the Shoulders of Giants includes On the Revolution of Heavenly Spheres by Nicolaus Copernicus; Principia by Sir Isaac Newton; The Principle of Relativity by Albert Einstein; Dialogues Concerning Two Sciences by Galileo Galilei with Alfonso De Salvio; plus Harmony of the World by Johannes Kepler. It also includes a biography of each featured physicist that explains the significance of his work.
